Title: Manufacture of valve seat
Inventor: HIROSE MASAHITO
IPC: B22F5/00
Filed: 1993-12-22
Abstract: PURPOSE:To increase wear resistance at parts as required without worsening machinability by strongly pressing the end surface of an intermediate on face part formed side so that a forged shrinkage tolerance at face forming part becomes larger than that at the other parts. CONSTITUTION:A punch 4 with a pressing part 4a at its lower end of the same form as the upper end and face part 1a of a valve seat to be manufactured is pressed strongly against the upper surface of an intermediate 2 held by a drag 3 with its face part 2a directed upward. By its strong pressing, a forged shrinkage tolerance H1 at an area where the face part 2a is formed is made larger than a forged shrinkage tolerance H2 of the upper end surface and, after forging, the density of the surface layer of the face part 1a is increased. As a result, while the face part 1a only is compacted, the other parts are not compacted. Thus the machinability is not deteriorated in finishing process, etc.

Title: Switching device
Inventor: KAWADA HARUNORI
IPC: H01L51/05
Filed: 1987-12-21
Abstract: PURPOSE:To obtain a switching device with highly reliable memory functions by a method wherein a periodical layer construction of organic insulator is provided between a pair of electrodes and memory properties are provided for switching characteristics. CONSTITUTION:Required polymer compound is dissolved in solvent such as chloroform, benzen, acetonitrile or dimethylacetoamide. Then the solution is spread over water 1 to form an organic compound film. Then partitions 3 are provided in order to prevent the spread layer from being diffused freely and spread too widely and the spread area is limited to control the concentration status of the film material and a surface pressure proportional to the concentration status can be obtained. While the surface pressure is maintained, a clean substrate 2 is gently made to ascend or descend vertically to the surface to transfer a single molecule film onto the substrate 2. By repeating this process, an accumulated film with the required number of accumulation processes can be formed. Thus, a potential barrier layer composed of an organic compound single molecule film or of the accumulated film of the single molecule films can be formed on the substrate.

Title: Waveform recognition type differential protective relaying device
Inventor: TSUJIKURA YOSUKE
IPC: H02H3/28
Filed: 1987-12-22
Abstract: PURPOSE:To effectively discriminate internal/external troubles by providing a CT (iron-core current transformer) saturation detecting means, CT saturation compensating means, and compensating the defective part of a terminal current due to the external trouble on the basis of the polarities of a CT saturation and a differential current. CONSTITUTION:In case of an external trouble, an erroneously differential current iD is generated by the CT saturation of the secondary current in of a terminal in which the external trouble occurs. The period of the saturation of the in and the polarity of the saturation are output from CT saturation detecting means 8 as a CT saturation detection signal sn. CT saturation compensating means 9 subtracts the current iD from the current in and outputs a current i'n of a compensation terminal as necessary of compensating the CT saturation if the iD is positive (negative) when negative (positive) CT saturation detection signal is input. In case of an internal trouble, since the CT saturation detection signal and the differential current have the same polarity, an unnecessary compensation is not conducted even if there is the CT saturation.

Filed: 1987-12-24
Abstract: PURPOSE: To detect a human immunodeficiency virus(HIV) antibody with high sensitivity by bringing a sample into contact with the slice of HIV particles and detecting the generated antigen-antibody complex by immunoassay. CONSTITUTION: A 700-900 A slice is prepared from HIV particles separated from HIV-infected human peripheral blood lymphocytes by using a low- temperature ultramicrotome. The slice is fixed on a slide and, after a serum from an individual which is suspicious of being exposed to HIV is made to react to the slice, the slide is washed. Then a fluorescent pigment-bound IgG is made to react to human immune globulin and, after washing, the intensity of the fluorescence is measured. When normal human lymphocytes are used as an indicator cell, antilymphocyte antibody can be detected.

Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To allow the electronic computer not to immediately display the calculation result of an inputted fractional expression, but to let a user experientially master a process wherein the fractional expression is simplified by reduction. SOLUTION: When an arbitrary fractional expression is inputted with keys and displayed at a liquid crystal display part 16 and a 'reduction' key 12c is operated, the retrieval of the greatest common measure between denominators and numerators by fractional terms and the retrieval of the greatest common measure between the denominators and numerators of fractional terms in multiplication relation are performed in previously set retrieval order after mixed fraction/improper fraction and division/multiplication conversion, and numerals of combinations of the denominator and numerator whose greatest common measure is detected first are blinked and displayed as a reducible point.  When the 'reduction' key 12c is repeatedly operated, the numerals of the denominator and numerator at the blinked and displayed reducible point are reduced and a next reducible point by the similar retrieval of the greatest common measure is blinked an displayed, so that a calculation result is derived and displayed by operating a '=' key 12d for a fractional expression which is simplified until it can not be reduced.
